General description

2-Chlorobenzoic acid degradation by pure cultures of Burkholderia cepacia strain with and without the bacterial hemoglobin gene was studied in parallel membrane bioreactors. Intramolecular hydrogen atom tunneling in 2-chlorobenzoic acid has been studied by low-temperature matrix-isolation infrared spectroscopy.

Application

2-Chlorobenzoic acid was used to study the degradation of 2-bromobenzoic acid by Pseudomonas aeruginosa.

A strain of Pseudomonas aeruginosa producing 2-bromobenzoic acid, designated 2-BBZA, was isolated by enrichment culture from municipal sewage. It degraded all four 2-halobenzoates as well as certain 3-halo- and dihalobenzoates, though none of the 4-halobenzoates supported growth of this organism.
